Enable)) be converted to electric current or power.In a second embodiment, board management device 108 not conversion processor computational load but instead
Notice 107 electric loading of VR controller will not become even worse.
Operational status information is transmitted to the controller 107 of voltage regulator 106 from board management device 108, not by processor 106
Domination, and also communicated with VR controller 107.As previously mentioned, this independent communication can by the second communication linkage 112 come
It realizes.
Board management device 108 is configured as controlling voltage regulator 106 based on operational status information.It is right by board management device 108
The control of voltage regulator 106 is to be transmitted to VR controller associated with each processor 102 according to by board management device 108
Computational load represented by 107 operational status information and carry out.That is, board management device 108 can be based on operational status information
The power limit of voltage regulator 106 is set.Processor 106 is allowed to control their corresponding voltages, while board management device 108
Corresponding power limit is set.Illustrate to be arranged by alignment processing device 102 by each power limit that board management device 108 is arranged dynamic

Board management device 108 can a kind of mode of power-efficient of optimization system plate 100 be related to using telemetry intelligence (TELINT) come to place
Manage the most effective to allocation processing workload of device 102 and voltage regulator 106.According to one embodiment, board management device 108 is connect
It is received in telemetry intelligence (TELINT) of the reception from voltage regulator 106 at board management device 108.Telemetry intelligence (TELINT) can be to provide about voltage tune
Save any information of some instructions of the efficiency of device 106.For example, telemetry intelligence (TELINT) may include the mobile layer of each processor 102
Grade, the input voltage of each voltage regulator 106, electric current and/or power, the output voltage of each voltage regulator 106, electric current
And/or the voltage of power, each processor 102, the electric current of each processor 102, the temperature of each processor 102, each tune
Save the temperature etc. of device 106.For example, telemetry intelligence (TELINT) can be transferred to the second communication linkage 112.
Board management device 108 is configured as being directed to the efficiency comes first of different electrical power mode based on voltage regulator 106 at
Manage device 102.That is, board management device 108 can use telemetry intelligence (TELINT) to determine which answers processor 102 and voltage regulator 106
This provides higher priority and which should provide lower priority to processor 102 and voltage regulator 106.Although
Each 102/ voltage regulator 106 of processor with identical efficiency to can nominally be operated in some conditions, still
Come there are a variety of causes so that 102/ voltage regulator 106 of processor is to will not nominally act.For example, each voltage regulator
106 one or more components (output inductor, output capacitor, input capacitor etc.) can become due to technique change
Change.It is faster than in addition, the physical layout of processor 102, memory 104 and voltage regulator 106 will lead to specific communication path
Other paths.According to one embodiment, board management device 108 is directed to the computation layer of different electrical power mode according to respective processor 102
Grade generates the distribution of the input power of each voltage regulator 106.That is, board management device 108 is collected in given power supply setting
Which executes to be better than the data of other pairs to processor 102 and voltage regulator 106 about, and the data are mapped as excellent
First grade scheme.
Board management device 108 is used based on priority and guides the plate data entered to processor 102, so that the plate number entered
According to the significantly more efficient processor 102 of voltage regulator 106 is directed to first, it is then channeled to voltage regulator 106 less
Effective processor 102.Priority application occurs over just the case where plate data for needing additional process resource to carry out processing entrance.
That is, board management device 108 adjusts the loading condition for applying and changing, therefore meeting only in response to the voltage at least one processor 102
Have benefited from indicating the precedence scheme which should use processor 102 and voltage regulator 106 first.
According to one embodiment, the plate data of the distribution based on generation, entrance are directed to processing by board management device 108
Device 102, so that the plate data of entrance are by first only in the case where needing additional process resource to carry out the plate data of processing entrance
The processor 102 for guiding the relatively low input power for having computation levels distribution to voltage regulator 106, is then channeled to voltage
Adjuster 106 has the processor 102 of the higher input power of computation levels distribution.This will be discussed for illustrative purposes now
The Working Examples that resource is offered as a tribute.It can be indicated on system board 100 by the distribution that board management device 108 generates with 80% peak power
Four processors 102 of the peak power consumption of two processors 102 to 40% of consumption are more efficient.Based on the knowledge, plate
Manager 108 guides the plate data of entrance to two significantly more efficient processors 102, so that these processors 102 will execute
It calculates, and two more inefficient processors 102 is deactivated or only additional process resource are being needed
It is used when handling input data.
In addition to above-mentioned priority of resource allocation Managed Solution, board management device 108 can be used for respective processor 102 independently
Control voltage regulator 106.It is communicated in second lacked between board management device 108 and board management device 108 and voltage regulator 106
In the case where link 112, voltage regulator 106 can be controlled only outside processor 106.In this case, voltage is adjusted
The electric source modes of device 106 are directly controlled by processor 102, but regardless of the efficiency and not of processor 102 and voltage regulator 106
The possibility distribution of the following processing request in guard system plate 100.System uses between board management device 108 and voltage regulator 106
Second communication linkage 112 overcome this defect, with accelerate instructed voltage adjuster 106 change power supply status processing and/
Or eliminate the unwanted transition of the voltage regulator 106 between power supply status.
According to one embodiment, in the power bracket of 102 input-bound of processor associated with the first VR controller 107
Before, operational status information (for example, instruction of the computational load for processor 102) is transmitted to from board management device 108 in advance
First VR controller 107.The operational status information transmitted in advance indicates processor associated with the first VR controller 107
102 expectations finally enter limited power bracket, and are maintained within the scheduled time cycle in limited power bracket.Base
In the information, the reduction of the voltage regulator 106 by the first VR controller 107 based on the operational status information control transmitted in advance
Power operational state be determined.According to another embodiment, enter in processor 102 associated with the first VR controller 107
After limited power range, operational status information is transmitted to first VR controller from board management device 108 by board management device 108
107.In this case, operational status information indicates 102 input-bound of processor associated with the first VR controller 107
Power bracket, and will be in the power bracket for being maintained at limited within the scheduled time cycle.In any case, it is based on plate pipe
The direct transmission for managing the operational status information between device 108 and the first VR controller 107, is controlled by the first VR controller 107
Voltage regulator 106 is operated under reduced power rating.First VR controller 107 can be instructed to be maintained at reduction
Until board management device 108 is indicated otherwise under power operational state.In this way, board management device 108 can be with overriding processor 102
Any instruction of the controller 107 of voltage regulator 106 associated with these processors 102 can be distributed to.
Using board management device 108, system can also accelerate voltage regulator 106 from various electricity using operational status information
The transition of source state.For example, board management device 108 forces the electricity controlled by the first VR controller 107 in advance according to one embodiment
Pressure adjuster 106 exits the power operational state of reduction.For example, this can occur in operational status information to board management device 108
In the case where indicating that the computational load being placed on processor 102 is coming.In processing associated with the first VR controller 107
Device 102 to voltage regulator 106 issue instructed voltage adjuster 106 should exit reduction power operational state order it
Before, voltage regulator 106 is forced to exit the power operational state of reduction.Advantageously, because board management device 108 is not according to for
The computation levels of the respective processor 106 of same electric source modes generate the distribution of the input power of each voltage regulator 106, institute
It can determine which processor 102 will move out the power operational state and which processor of reduction with board management device 108
102 will remain in the power operational state of reduction, therefore only voltage regulator 106 associated with these processors 102 changes
